Here in the north east we have fishing boats with single engine/props that go out for 1000+ mile journeys for weeks. ( think: Andrea Gail from The Perfect Storm ) I think a well cared for single engine boat is reliable enough that if you start thinking about get home engines you have to start considering other equally likely scenarios like lightning strikes, whale collisions and rogue waves. Every person has their own level of risk tolerance. You do what you can to minimize the risk and then you operate within your acceptable tolerance. You can never make ocean travel 100% guaranteed, ( think: Titanic ) you can just make it acceptable to your personal risk level, proceed to enjoy yourselves and accept the consequences of chance. There is a random component to just getting out of bed in the morning, and you have to strike the right balance between "carpe diem" and "cover your a#@"
